The 12GN series, a line of 12 mm geared DC micro motors, are for robotics and compact applications.
These high torque motors offer designers a space saving alternative to much larger brush motors. The 12GN motor measures only 12 mm x 10 mm x 29 mm from terminals to tip of shaft and weighs 8.7 gr. Starting torque is 300 mN∑m. Rated load is 20 mN∑m. Operation is quiet due to the close tolerance precision of the shaft rotation.
